South American Indians, members of an ancient empire (5)

I believe the answer is:

incas

(Other definitions for incas that I've seen before include "People of ancient Peru" , "People from Andes who settled in Peru" , "Peruvian natives" , "Old South American royals" , "Ancient Peruvians" .)

I've seen this clue in The Telegraph.
